ASSIGNOR TO DETROIT I-IOIST AND MACHINE COMPANY, OF DETROIT, MICHIGAN, ACORPORATION OF MICHIGAN.

TURN-TABLE-OPERATING MECHANISM.

To all whom it may concern:

Be it known that I, JOSIAH C. FLEMING, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State off/liehigan, have invented certain new and useful Improvements in TurnTable-Operating Mechanism, of which the following is a specification,reference being bad therein to the accompanying drawings.

The invention relates to a turntable construction wherein a tractor isemployed for rotating the same, and consists primarily in means forcushioning the impact of one of the members upon the other.

The invention further consists in the construction of the cushioningmeans, and still further in certain details of construction, and intheir novel arrangements and combinations, as will be more fullyhereinafter set forth and claimed.

In the drawings illustrating my invention,-Figure 1 is a side elevation.of an embodiment thereof; Fig. 2 is a plan view; and Figs. 3 and a aredetached perspective views of the joint parts.

In the drawings thus briefly described, A represents the turntable, B atractor of any approved type, including the usual traction wheel C and asuitable motor D for operating the same, and E is aconnection,preferably a hinged joint, -between the parts. In thepreferred form illustrated, the connection is composed of an attachingsection F rigidly secured to the turntable, including as a part thereofa laterally projecting block member G having vertical apertures a Z)formed therein.

H are spaced horizontally apertured ears upon the forward end of thetractor adjoining the table attachment, and T is a block connected by ahorizontal pivot J to the ears and by bolts K L to the block member ofthe attachment section F, the bolts passing loosely through theapertures.

As the locomotive moves onto the turntable, the latter is usuallydepressed. a certain amount, causing a sudden pull or shoe]: to betransmitted to the tractor. To obviate this. I have provided means inthe form of a cushion for yieldingly opposing the impact of the tableupon the tractor primarily upon the downward movement of the table. Thepreferred form is as illustrated, consisting of springs, as M,interposed between the Specification of Letters Patent.

Serial No. 583,234.

pivotblock I of the connection and bearings or abutments O at the upperends of the bolts, which are held in place by nuts as P. I alsopreferably, though not necessarily, employ similar means for opposingthe impact upon the upward movement of the table when the engine passesoff from the same. Such means are preferably coil springs, as Q, whichencircle the bolts intermediate the pivotblock I and the attachmentblock G, as plainly shown in Fig. 1. In the construction illustrated, itwill be readily apparent that the cushioning means serve to relieve theimpact of the turntable upon the tractor upon vertical movementof theformer in either direction, with the result that the tractor will not beappreciably affected by the shock or jar, and consequently thepropelling mechanism is protected from injury.

What I claim as my invention is,-

1. In turntable propelling mechanism, the combination with a turntable,of a tractor pivoted thereto, and means at the pivot for cushioning theimpact of one upon the other.

2. In turntable propelling mechanism, the combination with a turntable,of a tractor therefor, connection between the table and tractorincluding a bodily movable pivot member, and means for yieldinglyopposing movement of said member.

3. In turntable propelling mechanism, the combination with a turntable.of a tractor having a pivotal connection therewith, and means forcushioning the impact of the table upon the tractor upon upward movementof the table.

4-. In turntable propelling mechanism, the combination with a turntableprovided with an attachment section. of a tractor having its forward endadjoining said section, a horizontal pivot uniting the adjacentportions, and means for yieldingly opposing the impact of the table uponthe tractor upon vertical movement of the former.

5. In turntable propelling mechanism, the combination with a turntable,of a tractor, a connection between the tractor and turntable including avertically movable pivot member, and a cushioning member for yieldinglyopposing downward movement of said pivot member.

6. The combination wit-h a turntable, of a tractor therefor, anoperative connection between the table and tractor including ahorizontal pivot member movable bodily in a vertical plane, and meansfor yieldingly opposing movement of said pivot member in eitherdirection.

7. In turntable propelling mechanism, the combination with a turntable,of a tractor therefor, a vertical pivot uniting the tractor and table,and means encircling the pivot for cushioning the impact of the tableupon the tractor.

8. In turntable propelling mechanism, the combination with a turntable,of a tractor vertically pivoted thereto, and a vertically disposedcushioning member interposed be tween the portions of the turntable andtractor united by the pivot.

9. In turntable propelling mechanism, the combination with a tractor, ofa vertically rockable member carried thereby, the turntable, and avertical pivot uniting the latter 20 with the rock member.

10. In turntable propelling mechanism, the combination with theturntable, of a tractor therefor carrying a vertically IOCk. ablemember, a vertical pivot pin extending 25 through said member andengaging the turntable, an abutment upon the pin, a spring interposedbetween the abutment and rock member, and cushioning means positionedbetween said member and the turntable.

In testimony whereof I atfiX my signature in presence of two witnesses.
